24-bit Σ-Δ and simultaneous-sampling converters for seismic acquisition, downhole logging and energy infrastructure monitoring — resolution where it matters, supply where it hurts.
Energy exploration is a resolution game: seismic arrays resolve microvolt geophone signals across hundreds of synchronous channels, while downhole tools digitise sensor data in temperature and vibration envelopes that punish ordinary silicon. The converters at the core are 24-bit Σ-Δ ADCs — the AD7779 class for high-density array nodes, the ADS1278 class for wide-dynamic-range acquisition — plus wide-temperature simultaneous-sampling SAR parts for multi-sensor strings. For FAE-confirmed P2P mappings, SXA040 (24-bit, 8-channel, 144 KSPS, ADS1278-compatible) serves high-throughput seismic front ends and SXA030 (AD7779-compatible) serves array-node architectures. SXA6681AME is an AD7606-class wide-temperature option for multi-sensor strings; its P2P status requires separate FAE confirmation. Production status, batch consistency and 6-week lead time — because a survey season waits for nobody.

24-bit Σ-Δ classes (ADS1278 / AD7779 compatible) for microvolt-level geophone and sensor signals.
Simultaneous samplers with wide-temperature options for downhole string architectures.
8-channel integration per device cuts node BOM cost at survey scale.
Production status and 6-week lead time — deployment windows don't negotiate.
Yes — SXA040, 24-bit 8-channel Σ-Δ at 144 KSPS, pin-to-pin compatible with the ADS1278, suited to wide-dynamic-range seismic front ends.
SXA6681AME (AD7606-compatible 8-channel SAR with wide-temperature option) for multi-sensor strings, and SXA030 (AD7779-compatible 24-bit Σ-Δ) where resolution dominates. Share your temperature envelope for confirmation.
Our 8-channel-per-device integration is designed for dense node architectures. For array-scale programmes, we provide batch consistency documentation to keep thousands of channels comparable.
6 weeks standard. Plan qualification before the season — samples ship from production batches.
